Php Jquery datepicker beforeShowDay浏览器不一致和更新问题
我在jQueryUIDatePicker中遇到了一点问题,我试图突出显示由ajax调用确定的给定月份的空闲天数 问题有两个方面:Php Jquery datepicker beforeShowDay浏览器不一致和更新问题,php,jquery,jquery-ui,datepicker,Php,Jquery,Jquery Ui,Datepicker,我在jQueryUIDatePicker中遇到了一点问题,我试图突出显示由ajax调用确定的给定月份的空闲天数 问题有两个方面: beforeShowDay似乎只在Chrome中正确执行,而不是FF或IE,FreeDay类根本没有添加到这些浏览器中 即使在Chrome中,当滚动到上一个月时,自由日类也不会添加,直到返回到该月,换句话说,自由日不会在该月的第一个视图中突出显示。不过,这似乎并不是一个将持续一个月的问题 javascript // declare freeDays global va
// declare freeDays global
var freeDays = [];
// perform initial json request for free days
fetchFreeDays();
$(document).ready(function()
{
// fairly standard configuration, importantly containing beforeShowDay and onChangeMonthYear custom methods
$("#datepicker").datepicker({
changeMonth: true,
changeYear: true,
showOtherMonths: true,
selectOtherMonths: true,
dateFormat: 'DD, d MM, yy',
altField: '#date_due',

// query for free days in datepicker
function fetchFreeDays(year, month)

var start_date = '';
// if a month and year were supplied, build a start_date in yyyy-mm-dd format
if (year != undefined && month != undefined) {
start_date = year +'-';
start_date += month +'-';
start_date += '01';

$.each(data, function(index, value) {
freeDays.push(value.freeDate); // add this date to the freeDays array

// runs for every day displayed in datepicker, adds class and tooltip if matched to days in freeDays array
function highlightDays(date)
{
for (var i = 0; i < freeDays.length; i++) {
if (new Date(freeDays[i]).toString() == date.toString()) {
return [true, 'free-day', 'no to-do items due']; // [0] = true | false if this day is selectable, [1] = class to add, [2] = tooltip to display
}
}

几个月前我写了一篇关于这方面的教程,可能会有一些额外的信息,这是 问题在于
fetchFreeDays()
是异步的,因此可能$(“#datepicker”).datepicker()
在填充freeDays
数组之前就完成了执行,因此当页面第一次呈现时,您看不到任何内容
尝试将
$(“#datepicker”).datepicker()
放在$.getJSON
的回调函数中。仍然不太清楚。。。我在getJSON上实现回调时遇到了问题。现在,我已经尝试使用async:false选项切换到$.ajax,这似乎解决了在空闲日数组填充前几个月切换的问题,但我仍然无法在FF或IE中使用beforeShowDays。我已经将$('#datepicker').datepicker()放入在firebug中,我可以看到请求和响应看起来都很好,所以问题似乎出在highlightDays上。有没有任何原因可以解释为什么不同浏览器对toString行的处理方式不同?
// ajax.todos.php
$i = 0; // counter prevents infinite loop
$cutoff = '61'; // limit on timespan (in days)
$result = array();
// if date is provided, use it, otherwise default to today
$start_date = (!empty($start_date)) ? mysql_real_escape_string($start_date) : date('Y-m-d');
$check_date = $start_date;
$end_date = date('Y-m-d', strtotime("$start_date +$cutoff days")); // never retrieve more than 2 months
while ($check_date != $end_date)
{
// check if any incomplete todos exist on this date
if (mysql_result(mysql_query("SELECT COUNT(id) FROM " . DB_TODOS . " WHERE date_due = '$check_date'"), 0) == 0)
{
$result[] = array('freeDate' => $check_date);
}
// +1 day to the check date
$check_date = date('Y-m-d', strtotime("$check_date +1 day"));
// break from loop if its looking like an infinite loop
$i++;
if ($i > $cutoff) break;
